Mine Kafon; a bamboo tumbleweed that clears landmines:
The “Mine Kafon” is Massoud Hassani’s artificial tumbleweed, made from lightweight materials like bamboo. It is designed to be blown across uncleared minefields, detonating forgotten mines. It was Hassani’s grad design project for Design Academy Eindhoven. It continuously broadcasts its location, captured via GPS, plotting out safe, mine-free paths through the fields.
